Same story with me - I've got a GCV 190 on my Homelite 3100 PSI pressure washer - the kick-back wants to rip the handle out of my hand even with a death-grip on it. Does everything that Robert posted above regarding the 160 hold the same for the 190?
hppants, Having 0 exhaust valve clearance could cause poor compression, so why don't you just adjust the valves to specs and see if that solves your starting problem.
